    Phoronix: Some Distributions Still Live In A KMS-Less World

    One of the most commonly mentioned terms at Phoronix is KMS, as in kernel mode-setting, whereby the GPU mode-setting is done in kernel-space rather than user-space with an X.Org DDX driver. The major open-source drivers were quick to adopt KMS support in their DRM drivers since it allows for cool features like a cleaner boot process, faster and more reliable VT switching, more reliable suspend-and-resume, greater security by running the X Server as a normal user, the ability to have a Linux kernel panic message (like a Windows BSOD), and for new technologies like the Wayland Display Server to emerge. However, not all Linux distributions are yet on this KMS bandwagon...

    Take a look at the lists of bugs fixed in stable Mesa versions, and then say with a straight face conservative distros should ship the non-stable (.0) Mesa versions.

    How does not shipping the latest user space mesa code have anything to do with the in kernel DRM code we've seen talked about on the LKML?

    Or was that just another cheap self referring link?

    As for non-KMS-by-default, perhaps they just hate the Linux kernel DRM problems?
    What a stupid, unrelated, and totally shameless self-referencing plug.

    Agreed, this seems to be becoming more and more frequent on Phoronix. Shame on you Michael...

    The next release of Slackware (currently at rc3) I know has KMS on by default for the radeon drm. Either way, Zenwalk still has the support there, just not enabled by default, so who cares.

    I totally agree.

    Some chit-chat on LKML about the code which will be released in 3 months and likely adopted this fall with additional heap of fixes is not really worth a comment now.

    Wasn't referencing it in regards to that particular problem, but just the frustrations and DRM problems that many experience in general.

    Default cd media boot options

    My Windows 7 seems to be booting in a Vesa 800x600 mode prior to the actual desktop being displayed. I'm not so sure they are doing kernel-mode setting.

    I use the option 'vga=normal' for all of my Linux installations.
